Zorluk: OrtaMigration Discovery, Planning, and Tracking (Application Discovery Service, Migration Hub)

An energy utility company is migrating its regional billing system to AWS. The current architecture consists of 150 VMware vSphere VMs running Red Hat Enterprise Linux (RHEL) and Windows Server that host the web and application tiers, and 12 physical bare-metal servers running IBM AIX that host the core database engines. The security team has dictated two compliance requirements: (1) no software agents may be installed on the bare-metal database servers, and (2) the network team needs exact network dependency mappings (active ports, IP addresses, and connections) for the RHEL and Windows VMs to design target AWS Security Groups. The solutions architect must discover this environment, map the dependencies, and track the migration status from a centralized console. Which approach meets these requirements with the least operational effort?

  1. Deploy the AWS Application Discovery Agent on the VMware vSphere VMs to collect network dependency mappings. For the IBM AIX database servers, manually collect their specifications and network connections, and import the data into AWS Migration Hub using the import CSV template. Use AWS Migration Hub to track the migration.Cevap
  2. B
    Deploy the AWS Application Discovery Agentless Collector on the VMware vSphere vCenter Server to gather VM configuration and network dependencies. For the IBM AIX database servers, install the AWS Application Discovery Agent directly to capture database connections. Use AWS Migration Hub to track the migration.
  3. C
    Deploy the AWS Application Discovery Agentless Collector on the VMware vSphere vCenter Server. For the IBM AIX database servers, manually collect their configurations and upload them using the AWS Migration Hub import CSV template. Use AWS Migration Hub to track the migration.
  4. D
    Deploy the AWS Application Discovery Agent on all VMware vSphere VMs and the IBM AIX database servers. Enable agent-based discovery to stream all configuration, network connection, and process details directly to the Application Discovery Service. Use AWS Migration Hub to track the migration.

Cevap

Deploy the AWS Application Discovery Agent on the VMware vSphere VMs to collect network dependency mappings. For the IBM AIX database servers, manually collect their specifications and network connections, and import the data into AWS Migration Hub using the import CSV template. Use AWS Migration Hub to track the migration.
The correct option is correct because the AWS Application Discovery Agent supports Windows and Linux operating systems on VMware VMs and gathers the detailed network connection mapping required for designing target AWS Security Groups. Since IBM AIX is not supported by the Discovery Agent and security policies prevent agent installation on the database tier, manually collecting the database configuration details and importing them using the AWS Migration Hub CSV template is the only viable approach that fulfills all security and OS constraints.

Adım Adım Çözüm

1
Analyze VM discovery requirements
The RHEL and Windows VMs require network dependency mapping (IPs, ports, connections) to build security groups.
This requirement determines whether to use the Agent-based or Agentless discovery tool.
2
Evaluate AWS Application Discovery Service tools
Identify that the Agentless Collector only gathers configuration and performance metrics, while the Application Discovery Agent captures network connections.
Choosing the agent for VMs ensures that network dependency mapping data is successfully collected.
3
Evaluate AIX and bare-metal constraints
The IBM AIX servers run on bare-metal and cannot support the discovery agent, and installing agents on these database servers is blocked by compliance.
Alternative discovery methods must be chosen for the database tier.
4
Select data import method for database tier
Choose the Migration Hub CSV import template to record the configurations of the AIX databases.
Manual import is the standard method for recording servers that cannot run agents or agentless collection.
5
Consolidate monitoring
Integrate both the agent-based discovery data and the manually imported CSV data into AWS Migration Hub.
This provides a single dashboard to track the migration status of all assets.

Anahtar Kavram

AWS Application Discovery Service supports agent-based discovery (which captures process and network dependency details) and agentless discovery (which captures configuration and performance metrics for VMware VMs). When servers cannot run agents due to OS support (such as IBM AIX) or security policies, the AWS Migration Hub import CSV template allows solutions architects to manually add these assets to the migration inventory.
